Nothing is done about the key problems in fortbattles. I didn't test it, but I was asked to evaluate this by some guys on German server, so here is my preview of what I expect and what I think which should be done for the fortbattles. The range is still not a problem, because the malus is way to less. The bonus of a tower is about irrelevant. And now we increase the damage of everyone, so fortbattles will have around 20 to 30 rounds. But everyone is happy, cause of making more damage. Is it senseble? Not in any point. Does the defense probably win more battles? Possible, cause shooting first will now be a bit more valuable, but talking about sector bonus, the offense has still an advantage in that case.
So they key issues of the old formula were: Resistance was multiplied with 300 since 2013(!) the time of Natty, Munny, Johnson, where the AVG-Damage was around 300. So if we would make this factor dynamic and using the calculated average weapondamage from the fortbattle, we would see an improvement for the trial of resistanceskill, but it would still be taken down by LS-Players in Unionset. So probably we should go to the hitting/doding-chance-calculation. The Values of Stamina and Hiding were modified in 2013 from ^0,4 to ^0,6 and LS from ^0,4 to ^0,5 to weaken the bonus of the towers, cause both sides has higher base-values so the value of the towerbonus and range decreased. So why don't we take this step back? Just decrease the values to lets say ^0,4 again, it would massivly decrease the value of union in case of hitrate. The Damage per hit of Union would still be sick, but the hitrate wouldn't be that good. Cause to scale 900 Hiding or Setting Traps down to somewhat more close to 600(Livingston) you need to find a formula where the slope stagnate at some point.
Even making the bonus of towers dynamically could be an improvement, cause on new worlds (hopefully there will not be anymore) a fully builded fort is a fortress, cause the defense has about doubled up values on the tower in relation to the offense outside the fort.
So far I have to say I didn't calculated my suggested values, it's just about the direction in which I think the changes should be done.
